Project Introduction

The proposed project is aimed at investigating ways to accelerate the creation of SysML based models that can be used for model checking and more generally for Model-Based System Engineering. In the past few years, multiple projects in the ISHM domain as well as the operations domain (Procedure V&V) have started to leverage the power of model checking through the use of the Finite State Machines (FSM) formalism. These models have been typically developed manually by subject matters experts in the different spacecraft systems and subsystems. This is a significant hindrance to the widespread use of models for any targeted application. The envisioned suite of tools would allow non experts to derive the appropriate SysML models for their intended use. In addition to providing a generic library of space systems models, methods to customize these models to the specific target system, our proposal will also design tools that enable the automatic or semi automatic extraction of appropriate information from different source, thus significantly accelerating the development and the usage of such models.

Anticipated Benefits

The toolset for executable models development that can be customized to different systems will be useful within DoD organizations in which software intensive product lines are common. For example, the Unmanned Aerial Vehicles (UAV) Domain is enjoying a period of significant expansion. UAVs have progressed from target drones to reusable weapon systems. Their software systems have become complex and extremely diversified. Domain specific executable SysML models could reduce development risks by enabling many alternative operational concepts and designs to be evaluated before significant effort is expended developing poor designs. In the commercial arena, adopting the same type of approach for software intensive system can be used in a broad range of areas, such as airplane, power plant SCADA systems, and vertical business applications such as Human Resources applications. This type of technology can be adapted to these different domains and provide benefits similar to those provided to NASA.
